salomons are s916, not p16...p refers to the pivot heel of rossi/look bindings. regardless, 916s are a dope binding, i have a few pairs myself. id say right around 10-12 is good, depending on size/ability. i got mine all the way up to 16 cos they kept releasing at 14. my rossignol pro 180s are at 16 too. im gonna break my knees soon, but hey, at least im not gonna release.
